Class Information
Number: 548/574
Name: Organic compounds -- part of the class 532-570 series > Organic compounds (class 532, subclass 1) > Heterocyclic carbon compounds containing a hetero ring having chalcogen (i.e., oxygen, sulfur, selenium, or tellurium) or nitrogen as the only ring hetero atoms (class 540, subclass 1) > Hetero ring is five-membered consisting of one nitrogen and four carbons (e.g., halopyrrolidines, etc.) > Chalcogen attached indirectly to the five-membered hetero ring by acyclic nonionic bonding > The chalcogen is in a substituent attached to the ring nitrogen of the five membered hetero ring
Description: Compounds wherein the chalcogen (i.e. oxygen, sulfur, selenium, or tellurium) is part of a substituent which is attached to the ring nitrogen of the five-membered hetero ring.
